OPTICAL EYE-PROTECTING DEVICE.

Specification of Letters Patent.

Patented Nov. 19, 191s.

Application led September 13, 1917. Serial No. 191,108.

To all whom t may concern:

a citizen of the United States, residing at New York, in the county of New York and State of New new and useful Improvements in Eye-Protecting Devices,

of which the following is a specication.

The principal object of my invention is' to provide a convenient and useful eye-protecting screen to be worn by men operating acetylene torches and byothers under circumstances requiring protection to the eyes. Another Aobject ofy my invention is to provide an eye protecting screen that can be conveniently displaced for unobstructed vision when desired. Another object of my invention is'to providel such screen that shall be rugged in use, able to the head of the wearer. All these objects and others will be made apparent in the following specification and claims taken in connectionwith the accompanying drawings,'in which one specific embodiment of my invention has been illustrated. It will'.

be understood y that modifications can be made that will fall'vwithin the scope of the invention. I now proceed to describe the particular embodiment of my invention which is shown in` -the drawings. Figure 1 is a side elevationy partly broken away to show parts that would otherwise be concealed; 4

Fig. 2 is a top planfview; Fig. 3 is a front elevation; j Fig. 4 is a fragmentary side elevation corresponding to Fig."` '1, but showing a changed adjustment" of itheparts; and v Fig. 5 is a. verticall'fsction on' the line A 5-5 of Fig. 3 looking the direction of i the arrow.

to get a c orrect fit to the head of the wearer. Near their front ends the two-'side wires 11 have brazed thereto at 18 the lugs 17 which support the pivot pins 24.

VThe frame for the eye protecting screen is designated 19 and is ,made of refractory ber or other sheet material. that can be shaped as shown. The sides are bentas at 20 to prevent light from'getting tothe eyes,

The brackets 22 yare fastened by the rivets 23 to the frame 19 and their ends engage the pivot pins ,24 already mentioned and are secured by the nuts 25. On the pivot pins 24are the friction washers 26' and the nuts 24 are clamped tight enough so vthat .any angular adjustment of the parts on the pivot pins 24 will be maintained --against a moderate application of force but will yield to an excessive The extreme -front ends of the side wires 11 are bent around to form stops ,27to limit the downward angular adjustment of the screen 19. Therportions of the wires 11 between thevstops 27 andthe lugs '17 can be bent with pliers as atv 28 to adjust the stop position. y

Around the bottom and sides=of-each eye i opening 21 is a spaced ange 30 secured by rivets 31 forming a pocket to receive the, transparent medium. This pocket further completed by thev piece 32 across thetop.

f The transparent medium consists of. anfinner darkened glass plate 33 and a thinouter mica sheet 34.

end 37 adapted to form awretaini'rigcatch J projecting through the hole 36.

Thes'creen frame 19 is cut away at 39 for the nose of the wearer.y a f l The entire device as just described will be,` seen to consist of two principal parts, the head frame and the -screen pivotally connected thereto. The head frame is adjustable by bending In normal operative stops l27, which prevent it from resting on the noseof the wearer. In this position, the wearer will have a wide range of vision through the The leaf spring 3.5 hasf its;`

position, the screen will be in its lowermostv Aposition against the sheets 3i or the glass `ractory sheet material bent to glass and mica members and 3i. and it he is operating an acetylene torch, his eyes will be protected both trom the excessive light and from sputtering molten metal. iivhen the torch is extinguished or at any other time, if he wishes unobstructed vision, he simply pushes up on the trame 19, rotating it to the position indicated in Fig.

i, when he can ioolr ont under the screen' frame as he would under the visor of a cap. At no point does the screen come in contact with his tace, so that there is ventilation for his tace under the screen and there is no tendency to obstruct the flow ot perspiration on any part of his face. The outer mica sheets 3i protect the glass from spattering metal and can readily be renewed when desired. For renewing either the mica plate 33, the catches 37 are withdrawn and the parts can be slipped ont and in with the utmost facility. rlhe parts of the head frame that are close to the head are behind the screen so that they will not be uncomfortably heated by the heat radiated from the torch or other work.

l. in combination, a head fra-me and a frame for an eye protecting screen pivoted thereon and comprising a sheet of rigid material with two eye openings therethrough, said sheet being fiat around each of said openings but bent between them and notched at. the bend for the nose of the wearer, and with wings bent farther bach at the sides beyond the openings, and fiat pieces of transparent material across said openings.

2. n combination, a head frame and an eye protecting screen, said frame comprising a wire bent to form the sides and back and with another wire fastened across the front carrying a forehead `piece by a loose connection permitting said piece to adjustitself angularly to the forehead ot the wearer.

3. in combination, a wire head frame carrying two pivot pins, a dat piece of rea dihedral angle to form an eye protecting screen and two brackets xed thereon and rotatably ,mounted on said pivot pins.

e. ln combination, a trame adaptedjto i be. fixed on the head of the wearer, pivot pins carried thereby, one on each side at the trent, and a dat piece et refractory sheet material bent to a dihedral angle to :term an eye protecting; screen mounted to tnrn on said pivot-s.

ieeeeae front, a fiat piece of refractory sheet material bent to a dihedral angle to form an eye protecting screen mounted to turn on said pivots, and a stop carried'by said frame to limit the movement of said screen.

7. In combination, a head frame and an eye protecting screen, said frame comprising a wire bent to form, the sides and back and having its ends brought forward to act as stops, pivot pins carried by said wire back of said ends, and an eye protecting,r screen mounted on said pins and adapted at one adjustment to engage Said stops.

8. ln combination, in an eye protecting device, a `frame of heat resist-ing, non-heatconducting material having two eye openings and out away at its middle part to go over the nose of the wearer and bent back on each side, the axis of the bend being up and down above the cut away place, a head frame to be fixed on the head of the wearer to carry said first-mentioned frame, and

transparent members across said eye openmes.

9. In combination, a head frame and an eye protectingl screen, said frame comprising a wire bent to form the sides and back and having its ends brought forward to act as stops, pivot pins carried by said wire back of said ends, and an eye protecting screen mounted on said pins and adapted at one adjustment to engage said stops, said stops being adjustable by bending the same.

l0. In combination, a frame adapted to be fixed on the head of the wearer, pivot pins carried thereby, one on each side at the front, an eye protecting screen deeply notched at the middle on its lower edge to I go over the nose of the wearer, and brackets on the inner side of said screen and eingeg-` ing said pivot pins, said screen extending beyond said brackets and back of them and spaced from them so as to protect the brackets and the pivot pins from a source of heat at the trent of the wearer.
